Definitions

  • the present invention regards a method and an apparatus for folding metal rods in bars, in particular iron rods obtained through cutting from bars or reels.

  • the bars of the predetermined number can be of equal or different length with respect to the bars of the supplementary predetermined number. Instead, the bars inside each number to be folded, predetermined or supplementary predetermined, obviously have the same dimensional features.
  • the apparatus warrants the required versatility as it has a couple of folding benches at its disposal, which can be operated in line, at the side of the feeding line, independently and at the same time, and, if needed, which can be coupled in the movements as if they were a unique bench.
  • the method and the apparatus according to the invention allow to work pieces folded at only one end, by using the provided folding benches, independently from each other, to produce at the same time pieces of such a type, so doubling the productivity with respect to the known methods and apparatuses.
  • the same folding benches can work in an independent or combined and coordinated manner, to work pieces that require folds at both ends.

  • the group is mobile according to a relative motion, relatively to each fold unit provided, along the above said longitudinal direction, parallel to the feeding line to cooperate with both fold units, the first fold unit and the supplementary fold unit.
  • the intermediate handling group with double handling means is basically suitable to cooperate, at one side, with the first fold unit for folding the cited predetermined number of bars, and at the other side, with the supplementary fold unit to cooperate as well to the folding of the supplementary predetermined number of bars, by engaging respective portions of the bars.
  • the intermediate handling group is mobile with respect to the first fold unit and to the supplementary fold unit, in a way as to allow the moving and/or anyway the correct placing of the respective numbers of bars to be worked, with respect to the fold members.
  • the intermediate handling group is a group separated and autonomous from the fold units and from the respective folding heads, even though it cooperates in an autonomous way therewith.

  • An actuator controls the alternated operation of the tilting arm 30 from a lower position substantially horizontal to an upper inclined position.
  • the load portion stands at a height underneath the roller conveyor 3, in order to load the bars.
  • the load portion is suitable to rise with respect to the plane of the roller conveyor 3 until the cited upper position, thus lifting the predetermined number 2a of bars 2 or the supplementary predetermined number 2b of bars 2 above the fixed chute of the fold unit.
  • both folding benches 10, 20 positioned side by side are basically operated as previously described, to perform, preferably at the same time, two shaping cycles on the same apparatus 1 .
  • a further operating mode allows to obtain maximum length pieces using a fixed fold unit, for example the first fold unit 1 1 , in cooperation with one of the remaining available fold units of the other folding bench.
  • figure 15 illustrates the case wherein the first fold unit 1 1 of the folding bench 10 cooperates with the second fold unit 22, that is intermediate, of the supplementary folding bench 20, for obtaining relatively long shaped pieces 2' (see figure 15A), but having a length shorter than the maximum length possible for the apparatus 1 .
  • figure 16 illustrates the case wherein the first fold unit 1 1 of the folding unit 10 cooperates with the first supplementary fold unit 21 of the supplementary folding bench 20, at one end, in order to obtain shaped pieces 2' (see figure 16A) with a length substantially equal to the maximum one possible for the apparatus 1 .
  • the folding bench 10 instead of the supplementary folding bench 20 and vice versa, for obtaining similar combinations of shaped pieces as well as not shaped pieces.
  • the apparatus for folding metal rods in bars according to the invention therefore attains the scope of enabling to operate in an optimal manner the folding of rods in bars, in particular reducing at the maximum the space occupied and optimizing the productive yield.

Abstract

La présente invention concerne un procédé et un appareil permettant de plier des tiges de métal (2) en barres, destinés à fournir un nombre prédéterminé (2a) de barres (2) et un nombre prédéterminé supplémentaire (2b) de barres (2) à une ligne d'alimentation (3). Le procédé permet, en outre, le transfert desdites barres fournies au dit premier banc de pliage (10, 100) et à un banc de pliage supplémentaire (20, 200) de l'appareil pour exécuter leur pliage selon des cycles de pliage respectifs.
